Title: Improvements in or relating to methods and apparatus for making branched pipe fittings
Inventor: STANTON CHARLES BERNARD
IPC: B21C37/29
Filed: 1951-08-22
Abstract: 701,547. Making pipe fittings. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 22, 1952 [Aug. 22, 1951], No. 19818/51. Addition to 700,855. Classes 83 (2) and 83 (4) A method of forming a branched pipe fitting from a tubular blank by compressing said blank lengthwise in a main die cavity and applying pressure to a filler material to cause part of the blank to flow into at least one cavity branching off the main die cavity and supporting the whole of the blank throughout the forming operation as described in the parent Specification is characterized in that the portion of the blank not in contact with the wall of the main die cavity is supported throughout the forming operation by a plunger controlled by a profiled moving guide member. The operation and apparatus described in the parent Specification is modified in that the main die cavity 7 is formed by a split die 5a, 5b the die 5a containing a branch cavity 6. The tubular blank 1 is engaged by side plungers 8 having extensions 9 engaging an inclined guide 10 carried by a guide block 11 extending from the upper tool block 12 of the press. Lowering and raising the tool block moves the plungers inwards and outwards respectively. Distention of the tubular blank during the forming process is caused by high pressure fluid fed into the chambers 14 of containers 15 and the fluid passes into the blank through bores 16 in each plunger 8. The branch 3 of the fitting is supported during its formation by a support plunger 17 the receding movement of which is controlled by a wedge-shaped guide member 18 secured to the upper tool block 12. The movement of the upper tool block and thus the movement of the side plungers 8 and the support plunger 17 is synchronized with the release of the pressure fluid. The side plungers may be operated hydraulically ou pneumatically and the filler material may be water, soft metal or thermoplastic material.

Title: Navigation system with beacon identification
IPC: G01S1/02
Filed: 1958-06-20
Abstract: 848,150. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. June 20, 1958 [June 25, 1957], No. 19825/58. Class 40(7). The invention relates to radio navigational systems in which a beacon station comprises can antenna system for producing a rotating asymmetrical radiation pattern and means for transmitting reference pulse signals when the pattern is in a predetermined position. A particular example of such a system is that known as TACAN. According to the invention the beacon also transmits identification pulse signals which have a repetition frequency which is harmonically related to the repetition frequency of the reference signals and, in order to prevent distortion of the audio tone derived from the identification signals at a co-operating receiver, the reference signals and identification signals are locked in phase. In one embodiment a TACAN beacon 1 and aerial system 2 produce a rotating nine lobed radiation pattern having one of its nine lobes larger than the rest. When the larger lobe passes through the reference direction a pulse forming arrangement 28 triggers pulse generator 22 which emits a characteristic reference signal. The passage of the other lobes through the reference direction similarly coincide with an output pulse from arrangement 26 which triggers pulse generator 23 to produce a second form of reference signal. At the receiver 31 comparison of the amplitude variation of the received signal with the times of arrival of the reference signals and second reference signals give coarse and fine bearing indications respectively. Range information may be obtained by transmitting pulses from the receiver location to interrogate a responder at the beacon. The speed of rotation of the aerial pattern in this embodiment is such that the reference signals produced in generator A are repeated at the rate of 135 cycles a second. The identification signal frequency is made 1350 c/sec. and is produced in oscillator 11 the output of which is modulated by mechanical keying device 18 to give a code signal identifying the beacon. The modulated signal is fed to multivibrator 12 to produce output pulses which are coded and transmitted in the same way as the reference signals. At the receiver the detected pulse signals are passed through a pulse amplifier and clipper 38 to ringing circuit 39 which regenerates the 1350 c/s. modulated audio signal. Two ways of synchronizing the phases of the identification and reference signals are described. In the first of these (Fig. 4, not shown) the output of pulse forming arrangement 26 is fed to synchronize oscillator 11 at a frequency exactly the tenth harmonic of the second reference frequency. In the second (Fig. 5, not shown), the output of oscillator 11 is fed to a count down 10: 1 phantastron frequency divider which provides one input to a phase discriminator. The second input for the discriminator comes from arrangement 26 and the discriminator output is used to control the drive motor 29 of the rotating aerial system so as to ensure the required phase relationship.

Title: Improvements in or relating to double row roller bearings
IPC: F16C33/46
Filed: 1950-08-14
Abstract: 679,700. Bearings. WALLGREN, A. G. F. Aug. 14, 1950 [Aug. 15, 1949], No. 20134/50. Class 12 (i). A double-row roller bearing comprises conical rollers 14, of which only one row is shown, separated by supporting members 28 integral with a holder ring 30 running on a surface 32 on the inner race, the supporting members 28 being broader towards the centre of the bearing, when viewed axially, than at its outside edges. The shape of the supporting members 28 thus prevents the holder ring being withdrawn while the bearing is in operation. Spaces 34 in the holder-ring allow the bearing to be lubricated. The supporting members 28 are inserted between the rollers 14 by elastic deformation of the ring 30 to the shape shown in dotted lines, for which purpose a tool is described (Fig. 7, not shown). The holder ring and supporting members may be made from bronze alloy. Alternatively the holder ring 30 and supporting members 28 may be made separately from e.g. steel plate (or sheet iron) and bearing bronze, the outer ends of the supporting members being formed as pins received in openings in the holder ring, in the outer face of which the pins are riveted over. The invention may also be applied to double-row roller bearings having the larger ends of the rollers turned outwardly, instead of inwardly as shown, and to double-row roller bearings having a spherical roller track on the outer race. Specification 629,547 is referred to.

Filed: 1920-07-10
Abstract: 148,467. Weise S÷hne, and Lawaczeck, F. June 27, 1916, [Convention date] Fluid bearings.-A fluid-pressure thrust bearing for shafts &c. comprises a balancing piston b, Fig. 1, carried by the shaft a, the piston being grooved to pump oil &c. into a pressure-chamber c. According to the displacement of the shaft, the width of the throttle-clearance c varies, and consequently the pressure. In a modification, an auxiliary groove-pump f is provided on the shaft which also tends to force oil into the pressurespace e, so that the width of the throttle-clearance can remain relatively large. In the form shown in Fig. 2, both pumps b, f force oil into the pressure space e, and the throttling device consists of an aperture g, the section of which may be made as small as desired. In this case, the automatic throttling action is provided by the distance between the front of the piston b and the face of the aperture g.

Title: Improvements in transmitting apparatus for the television of motion-picture film
IPC: H04N3/38
Filed: 1944-10-23
Abstract: 608,939. Television transmitters. GENERAL ELECTRIC CO., Ltd., and JESTY, L. C. Oct. 23, 1944, No. 20490. [Class 40 (iii)] In television transmitting apparatus of the kind in which a continuously moving film is scanned interlacedly by an electronic scanner, means are provided to compensate for imperfect interlacing due to shrinkage and, or, expansion of the film. Frame synchronizing pulses from terminal 10 control a saw-tooth generator 12 at frame frequency and a square-wave generator at half this frequency, Figs. 1 and 3. These waveforms are shown at (b) and (a) respectively, Fig. 2. The output from 14, through the potentiometer 15, is applied to the deflecting coils 16 in parallel with the outputs from 12 and when these two outputs are of equal value the waveform of the current through 16 is as shown in full lines in Fig. 2 (c). When film shrinkage occurs, perfect interlacing on alternate frame scans is brought about by adjustment of 15 so that the amplitude of 20<1> becomes 20<11>. Alternatively, the frequency of the saw-tooth wave generated by 12 may be halved and its amplitude doubled, the output of 14 normally being zero except when shrinkage occurs when it is increased from zero and in opposite phase to Fig. 2 (a) by a suitable amount. Means in which variation in the film length causes movement of an idler roller may be utilized to produce an indication of shrinkage and/or automatic adjustment of 15. In an alternative arrangement, Fig. 3, providing automatic compensation for film length variation, two electric pulse trains are produced by photo-electric cells 35, 38, co-operating with light sources 31, 32, which are modulated by the passage of the filmsprocket holes. The outputs from the photoelectric cells after amplification and limiting are fed to a phase discriminator 43 giving a D.C. output voltage which is zero when the pulse trains are in phase and increases with increasing phase difference. The D.C. voltage is applied as a control voltage to an attenuator 44 which fulfills the same function as resistor 15 in Fig. 1. The attenuator may comprise a variable Á thermionic valve, the gain of which is controlled by the D.C. voltage from 43. Instead of electronic compensation, movement of the sprocket 24, Fig. 3, may be transmitted by suitable means to the control member of 15, Fig. 1. When a cathode-ray tube employing electrostatic deflection is used the wave-forms shown at Fig. 2 will be those of voltage and not current, the outputs of 12 and 14 being then connected in series.
